| Popis: | 100 This paper studies the relationship between surface grinding machine vibration signals with the workpiece surface quality. Surface grinding machine vibration signal analysis, the completion of the extraction workpiece quality status and grinding machine state of the statistical characteristics of parameters, a variety of workpiece quality of completion status, such as mirror, scratches, flutter pattern, matte, and burn the statistical characteristics of the statistical characteristics of parameters The parameters of the sample in the state database, and into the statistical process control statistical control charts, maps and histograms for state classification and diagnosis. Finally, written with LabVIEW software virtual instrument system, man-machine interface operation module, signal acquisition and signal analysis module, the NI 9174 module hardware settings, and integrated Web-based intelligent process monitoring system through the LabVIEW software to build surface grinding machine spindle, the processed signal of the measuring surface grinder for extraction job completion status and machine processing statistical characteristics of parameters, a variety of workpiece quality of completion status, and statistical process control charts, maps and histograms, graphical display of time-frequency analysis man-machine interface for real-time monitoring of the grinding process and completion of the surface state of classification and diagnosis. |
